comments: One of the early delights that I learned in working wood was the ease with which it was possible to incise a straight groove into a flat surface with a router. This basic operation, widely used in furniture making for both construction and simple decor, is less often used as the primary technique for creating more-complex abstract designs. In this case, I was intrigued by the way a pair of radiating straight line sets led to irresistible images of curvature and three-dimensionality. The main work is delineated by one-eighth inch smoothed and yellow-painted half-round grooves. The yellow and black surface fields are wood stain introduced to enhance contrast and depth. The frame, created as an integral part of the work, features 90° V-grooves in yellow and green.
